JOHN ANDERSON, OF NEWGASTLE-UPON-TYNE, ENGLAND.

MACHINE FOR ORNAMENTING TURNED PILLARS.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed August 25, 1905. Serial No- 275,841.

To all whom it may concern:

Be it known that I, JOHN ANDERSON, a subject of the King of Great Britain, residing at Pottery Lane, Newcastle-upon-Tyne, in the county of Northumberland, England, have invented a new and useful Machine for Ornamenting Turned Pillars and the Like, of which the following is a specification.

My invention relates to machines for ornamenting turned pillars and the like of the kind wherein a pair of head-stocks are adjustably mounted on a slide designed to be traversed in front of a stationary revolving tool in a frame which is itself movable in a guide in the bed of the machine in a direction at right angles to that in which the head-stocks and work are traversed.

According to the invention the pillar or other work to be ornamented is fixed in the usual way between the centers of the head-stocks, the spindle of which is provided with a plate notched at the periphery, which I term the division plate, these notches engaging a pawl in connection with an arm on the said spindle. A guide or templet is provided which is fixed to the frame and is provided with a sliding socket which engages with the aforesaid arm which rotates the pillar or other work, when the slide is traversed by hand.

In the accompanying drawing:Figure l is a front elevation of a suitable form of machine constructed according to the invention. Fig. 2 is a plan view thereof. Fig. 3 is an end elevation of the machine. Fig. 4 is a front view of the division plate drawn to a larger scale.

a and b represent the two head-stocks and c is the slide upon which the said two head-stocks are adjustably mounted through the medium of the bolts 0! and groove 0.

f is the frame in which the slide 0 is mounted, the said frame being provided with the bar or foot 9 which works in the guide it formed in the bed i of the machine in a direction at right angles to that in which the slide 0 is traversed in the frame f.

j is the division plate which carries one end of the work and which is loosely mounted upon the spindle j in the head-stock b, the said division plate being provided around its periphery with a series of notches is one of which engages the pawl Z. The pawl Z is pivoted to an arm )n which is secured to the spindle j. n represents the carriage for the rotary cutter 'n, this device being of any suitable description.

0 is the guide or templet and o is the socket or sliding member which slides thereon andalso has a longitudinal sliding engagement with the aim m.

The guide or templet 0 is clamped by clamping plates 7 p, q, q, and bolts 1' 1' to brackets s, s, bolted to the frame f, the said brackets being of circular form concentric with the spindle j and provided with slots 15, t in which the clamping plates p and q can be adjusted according to the shape of the templet. To facilitate clamping the templet 0 the end portions thereof are conveniently provided with spherical portions u it which may be integral with the templet or secured thereon in any suitable way, the said spherical portions being gripped by the clamping plates p, q.

The machine operates as follows, that is to say, the pillar or other work to be ornamented is fixed between the head-stocks a and b in the usual way and is brought into the proper position with respect to the tool by means of the division plate and the sliding bar or foot 9 and frame f; the slide 0 is traversed by hand in the frame f whereby the work is moved axially and simultaneously turned by thetemplet n in front of the cutter n which thus cuts an irregular spiral or other ornamentation or molding upon it according to the shape of the said templet. The bar 9 serves to keep the frame f in place and also enables the work to follow the cutter in cases where the said work is taper or of irregular profile.

What I claim and desire to secure by Letters Patent is:

1. In a machine of the kind described, the combination with a frame, of a slide mounted thereon, a pair of headstocks mounted on said slide, a spindle revolubly mounted in one of said head-stocks, an arm rigidly secured to said spindle, a guide rigidly secured to said frame and extending longitudinally of said slide, a sliding member engaging said guide and provided with a telescopic connection with said arm on said spindle and a cutter angularly disposed to said slide, substantially as described.

2. In a machine of the kind described, the combination with a frame, of a slide mounted thereon, a pair of headstocks mounted on said slide, a spindle revolubly mounted in one of said headstocks, a division plate loosely mounted on the end of said spindle, and provided on its periphery with a series of notches, an arm rigidly secured to said spindle adjacent to said plate, a pawl pivoted to said arm and adapted to engage a notch in said plate to lock said plate and arm together, a guide rod secured to said frame and extending longitudinally of said slide, a sliding member working on said guide rod and provided with a socket portion for receiving the end of said arm on said spindle and a cutter angularly disposed to said slide, substantially as described.

JOHN ANDERSON.
